Contextual model-based event scheduling

ABSTRACT

Various techniques for performing contextual event scheduling with an event scheduling service are disclosed herein. In an example, data is processed at an event scheduling service, based on the use of a trained machine learning model that is specific to a user. This trained machine learning model is operated by the event scheduling service determine a proposed time and proposed scheduling parameters based on the contextual information, to identify a proposed event time and event scheduling parameters based on the model, the data indicating a user state, or external data. Further examples to evaluate user activity and identify schedule characteristics based on data inputs from a user&#39;s mobile computing device, wearable sensors, and external weather, traffic, or event data sources, are also disclosed.

TECHNICAL FIELD

Embodiments described herein generally relate to scheduling and communication functions implemented on electronic devices and, for some examples, the control and operation of scheduling and communication software features for conducting an electronic communication event with devices such as mobile smartphones, wearable devices, and related data communication systems.

BACKGROUND

A live audio conference (e.g. a phone call or voice-over-IP session) is frequently used as a means of communication by human users. Although people rely on this form of communication at multiple times of a day, a contacting user is typically not aware of the availability constraints of the contacted user before the call is attempted (such as whether the contacted user is participating in an ongoing meeting, located in a noisy environment, involved in a current activity, etc.). As a result, time and effort is often spent in exchanging back-and-forth communications between people (or human assistants) to identify the optimal time for a call or session—often through the manual exchange of verbal messages or digitally written communications.

Some computerized programs provide event scheduling features that consider a contacted user's calendar status and constraints. However, existing digital assistant solutions and calling applications often perform this determination using outdated or incomplete information. As a result, many types of scheduling activities are still performed manually with human intervention. This requires extra effort for the user, inefficiencies with communication devices and networks, and ultimately, does not avoid missed communication opportunities.

DETAILED DESCRIPTION

In the following description, methods, configurations, device components, and related apparatuses are disclosed that provide contextual event scheduling using data processed at an event scheduling service, based on the use of a machine learning model. This data is processed based on offline data training of the model and online data provided to the model from various user-specific and user-generic (e.g., external) data sources. As a result, a logic rules-learning model may be used to identify and apply an appropriate scheduling time and parameters for an electronic communication event, based on historical and real-time data inputs from user devices. This may assist users (and the electronic devices operated by the users) to identify and utilize a best contextual and semantic time to conduct a communication event such as a phone call, videoconference, chat session, or the like.

In an example, the presently described techniques and configurations are applied to enable a virtual computerized assistant, scheduling program, communication program, or other software utility, to consider a context, calendar availability, calling patterns and routines for the scheduling of events—for a single user or even between two users. Such functionality is not provided in current digital assistant products such as Google® Now, Apple® Siri, Microsoft® Cortana, or in phone or voice-over-IP applications Skype™, Viber™, Tango™, and the like. Rather, current digital assistant products do little more than display availability from a user's calendar (if calendar information is available). The presently described techniques describe the technical infrastructure used to perform intelligent and context-sensitive scheduling of an electronic communication event, with the context being determined from a combination of real-time and online data, and processing of such data from historical data trained models.

As an example of usage of the present techniques, for many users, a preferred time for conducting an electronic communication event (e.g., a phone call) may be based on a user's schedule that has repeating characteristics. For some users, this may occur during a repeating routine of the user, such as a given time of the day, at lunch break, after a commute, or the like. For other users, the preferred time may be based on a given context of user activity, such as talking while driving, at home, etc. The historical data from user routines and the current data from user activity context may be analyzed and provided to a scheduling service for use in a trained machine learning mode. Data related to the availability constraints of the user, the other user, or other participants in a group such as an ongoing meeting, activity, environment, and the like may be processed and evaluated with the trained machine learning model. Further, data from external sources related to user activities, scheduling constraints, or communication preferences may also be processed and evaluated by the scheduling system.

Compared to the existing state of the art, the techniques described herein enable improvements to the operation of scheduling and communication software operating in computing devices, telecommunication networks, and data processing systems. These improvements also provide accuracy and performance benefits to the logic, search, and analytic functions performed in such devices, networks, and systems. Such features also improve the functioning of the hardware and software within the respective devices, networks, and systems, through reduced processing resulting from an improved accuracy in scheduling operations, reduced bandwidth and hardware usage by electronic communications, reduced (data-driven) user interactions, and improved success and accuracy of electronic communication sessions.

FIG. 1 illustrates an overview of an example communications environment 100 including processing and interactions among a computing device 110 (e.g., a smartphone), a wearable device 130 (e.g., a smartwatch), and an event scheduling service 150 (e.g., a cloud-based server), for implementing the presently described event scheduling techniques. It will be understood that additional components and circuitry not depicted in FIG. 1 may be used to implement the following data processing and communication techniques.

The computing device 110 is depicted as a smartphone, but in other examples, may be a desktop or notebook personal computer (PC), a tablet, a thin client device, or other form factor including an integrated or separate display screen. As shown, electronic communications with the computing device 110 may include communications 111 between the computing device 110 and the wearable device 130 (e.g., wireless communications using Bluetooth, Wi-Fi, near field communications (NFC), etc.), and communications 112 between the computing device 110 and the Internet/WAN (wide area network) 120. The computing device 110 may be communicatively coupled to other devices (not shown) via wired or wireless connections that communicate a digital signal.

The wearable device 130 is depicted as a smartwatch, but in other examples, may be provided in a smart bracelet, clothing, accessories, or in a standalone device form factor that is not necessarily wearable. The wearable device 130 may include or be coupled to at least one sensor (e.g., integrated within the housing, assembly, or unit of the wearable device 130), including sensors to detect physiological characteristics of the user (e.g., through a heart rate monitor, temperature sensor, activity sensor) or environmental characteristics of the user's environment (e.g., through an accelerometer, gyroscope, etc.). The wearable device 130 may also include at least one output medium, such as a touchscreen display 132, and at least one input medium, such as buttons exposed from an exterior of the wearable device 130 or touch input locations recognized by the touchscreen display 132. Other types of sensors and input/output mechanisms not depicted in FIG. 1 may be included in or coupled to the wearable device 130.

The sensor data produced from among the respective sensors of the wearable device 130 may be communicated to the computing device 110 via the communications 111. This sensor data may be used indicate real-time context information and user state that is relevant to scheduling operations. In certain examples, based on the number of sensors and the data processing involved, the wearable device 130 may perform electronic operations to process the sensor data directly at the wearable device 130. In other examples, the wearable device 130 may relay the sensor data to the computing device 110 for processing (including in scenarios where the computing device 110 further transmits the sensor data to a remote service for analysis).

The computing device 110 utilizes the communications 112 with the Internet/WAN 120 to connect to data services offered by the event scheduling service 150. The event scheduling service 150 may host and train scheduling models, process scheduling data with the scheduling models, and generate a proposed schedule/reschedule or proposed communication parameters (including time/date and medium characteristics) for an electronic communication event. The event scheduling service 150 may include features of a server computing system 154 to execute logic and perform analysis of event scheduling data models, a data store 156 to store the event scheduling data models and collect information related to the event scheduling functions, and machine learning models 158 that are stored, hosted, or persisted to facilitate the evaluation of scheduling data. Other features of the event scheduling service 150 not shown may include server management features, application programming interfaces, network data and processing balancing features, and other aspects of a server-/cloud-based processing system.

The computing device 110 is depicted as being connectable to a plurality of other communication devices associated with other users 140, with such other communication devices accessible via respective types of electronic communication mediums. The proposed electronic event scheduling operations, implemented with the event scheduling service 150, are performed to facilitate communications between the computing device 110 and the other communication devices (142, 144, 146) via these electronic communication mediums. For example, the other communication devices may include a mobile phone 142 accessible via a connection 113 with mobile phone (e.g., cellular) wide area voice and data networks; a phone 144 accessible via a connection 114 with landline (e.g., Plain Old Telephone System (POTS)) phone networks; and a computing device 146 accessible via a connection 115 with a wide area network (e.g., wired or wireless Internet connection).

FIG. 2 illustrates an example use case scenario 200 performing scheduling functions in a machine learning model with online and offline logic. In an example, the use case scenario 200 for scheduling or rescheduling an electronic communication event (such as a phone call) between two or more people may be used to locate a best fit for respective users' routine, needs, context and availability constraints. The operation of the use case scenario 200 may be facilitated by user interaction with an event scheduling service that operates machine learning models and logic, based on the following example.

As shown, the use case scenario 200 of FIG. 2 includes a series of data flows occurring from external state sources 210 and user state sources 250, which provide data for use with offline logic 220 (e.g., historical data model training through behavioral learning) and online logic 240 (e.g., real-time data model evaluation). The logic 220, 240 uses the information that is stored for two or more users to schedule or reschedule an electronic communication event (e.g., phone call) between them, at time slots that fit with each user's planned day. The logic 220, 240 evaluates the elements in the user's day and evaluates the user's common behavior for performing the communication with other people (the callees). From this logic, the scheduling system generates identified schedule characteristics 270 that indicate optimal times for the electronic communication event based on one (or both) party's availability characteristics. These availability characteristics may include schedule availability (based on calendar meetings), planned locations, nature of relationship (e.g. family, friends, colleagues, etc.), planned activity (e.g. driving, running), routine behavior (e.g. usually talk during work hours), and the like.

The offline logic 220 may be implemented in a scheduling system to perform user-customized machine learning training 222, such as to refine and improve the user-based machine learning models 232. These machine learning models may be stored in a database system 230 within the scheduling system. The offline logic 220 operates as a behavioral learning component that is adapted to a particular user through the use of the machine learning training 222. Such training takes into account the historical behavior of each user and the user's co-behavior of establishing a communication (e.g., a call) and the different contexts and states for making such communication. These data are processed and input to a personalized machine learning model for predicting the optimal time to make or reschedule a communication based on past behavior.

The online logic 240 performs functions to identify a schedule or schedule characteristics 270 for an electronic communication event. The online logic 240 may operate to compute recommended “optimal” timeslots for the intent of the communication (e.g., to schedule a communication after a particular activity). In an example, an optimal timeslot for the rescheduled event may be automatically “anchored” on the user's timeline (timeline 242). This may be performed with an “anchoring” component that considers a current user context, calendar availability of all involved users, planned activity of all involved users, and a prediction of the pre-trained machine learning model (data 244) for a future user context.

The offline and online logic modules 220, 240 receive data from mobile devices 252 and wearable sensors 254, as well as external state sources 210 that provide global data (e.g., applicable to multiple users). The data from a mobile device 252 and wearable sensor 254 of a particular user may include calendar appointments, tasks, phone calls, text messages, emails, location, connectivity (e.g., Wi-Fi/cellular, Bluetooth) information, activity (driving, running, etc.) information, environment noise, physiological data (e.g., pulse, body temperature, stress, sleep), and the like. This user-specific data is enhanced with the addition of data from external data sources such as weather data 212, public traffic data 214 or like transportation schedules (e.g., transit, flight schedule and locations), and known event data 216 that indicates events for the user or in proximity to the user. For example, if a user is driving in a traffic jam, the user may be able to immediately talk on a phone call; if weather conditions near a user are inclement, then a user may not be able to talk for a period of time (or may arrive late to a meeting); if a user is scheduled to attend an event that is busy, then the user may not be able to schedule a phone call immediately prior to or after the event.

The offline logic 220 and the online logic 240 also may be further customized for purposes of scheduling a voice communication event, particularly, a telephone or voice-over-IP call. With use of the offline logic 220 and the online logic 240, contextual constraints of the user to participate in a voice conversation may be taken into account, even though the user may have his or her phone at all times of the day and the user's phone call is capable of ringing at all times. For example, the voice call may be a phone conversation that a user would rather take at home, when driving, or before working hours. The learning algorithm considers both users' activity context in addition to the users' availability, and identifies an optimal (and recommended) scheduled time for the phone call. Thus, although calendar availability may show that the users are available at all times, the evaluation of user behavior and context may be used to redirect the call to a preferred time from the perspective of both users.

Aspects of the previously described offline logic 220 and online logic 240 may be implemented as part of an event scheduling service, such as the event scheduling service 150 depicted in FIG. 1. However, other aspects of the offline logic 220 and online logic 240 may be integrated for use with an intermediate computing device, software programs and logic executed on the mobile devices and wearable sensors 254, or directly into communication services (e.g., information services provided by communication or internet service providers).

FIG. 3 illustrates an example sequence diagram 300 of communications performed to support a machine learning model using offline logic, according to an example. The sequence diagram 300 specifically illustrates a sequence of communications performed to support a machine learning model of scheduling and rescheduling functions based on offline logic.

In an example, the sequence diagram 300 may integrate the features of the offline logic, online logic, database, and external sources depicted in FIG. 2. As depicted, the sequence diagram 300 includes a first user, User A 302, operating one or more devices, User A devices 304; and a second user, User B 312, operating one or more devices, User B devices 314; online logic 320, a database 330, and offline logic 340; and external data sources 350.

Further to the examples of offline logic discussed above, the offline logic 340 in the sequence diagram 300 is used to obtain data and train a supervised machine learning model based on past behavior, activity, and context. For example, the machine learning model produced by the offline logic 340 may reflect patterns in the user's behavior regarding voice call events, by evaluating the actual voice calls that the user has performed in the past. This model may identify concepts such as: a user tends to answer calls from the user's workplace while driving; a user calls a specific phone number when leaving a work place; User A talks to user B on the phone every work day between 10:00 and 10:30 am; User C immediately returns calls from User D; and the like. The model and data needed to use it is stored in the database 330 for online use (e.g., for access and consumption by the online logic 320).

As a further example, the offline logic 340 and its inputs may also be used to assess the historical behavior of a user related to a communication event and the context of the communication event. For instance, if user Bob receives a phone call from his friend John while exercising on Wednesday evening, then the offline logic 320 may record the context of the communication (Wednesday, Evening, at the Gym, Exercising) and the specific caller (John). The historical contextual information for user Bob may indicate, however, that user Bob prefers to take calls from other callers (Mary, Joe, unknown callers) after exercising, as determined from a prior recorded behavior—such as from a Wednesday night where Bob chose to call Mary immediately after exercising and a Thursday night where Bob chose to call Joe 10 minutes after exercising.

Data is reported to the offline logic 340 by User A devices 304 (e.g., mobile/wearable sensors) through the use of online user data/state reporting 352, and by User B devices 314 (e.g., mobile/wearable sensors) through the use of online user data/state reporting 354. The offline logic 340 also requests data 356 and receives external data 358 from external data sources 350. Based on the data inputs from the reporting 352, 354 and external data 358, a machine learning model is calculated, trained, and stored 360 in the database 330. This training process may occur periodically to keep the model updated.

In an example, the online logic 320 operates to assist a scheduling operation in response to a user request to schedule an electronic communication event with another party. Current and future time slots for the communication event are evaluated by the model generated from offline logic 340 and ranked by their suitability for the type and characteristics of the event (e.g., a phone call). A scheduled time slot may be suggested to the user by order of suitability or the best time slot may be chosen automatically. The time slots may be either a specific hour (“16:30”) or a semantic text string (“after the meeting”) that has a contextual, relative, or temporal meaning.

In contrast to this approach, existing solutions today for scheduling events only take into account a user's calendar availability. Many types of communication events such as phone calls have constraints that do not apply to face-to-face meetings, such as: required duration for the call, tendency to talk during another activity (e.g. while driving), preferred locations for the call (work, home, car) and environmental constraints (such as noise). Existing digital assistants enable users to set up call reminders but require specifying the exact time for the call reminder. The online logic 320 and the use of a trained data model operates to evaluate the relevant information regarding all required attendees of the event and schedules (or re-schedule) the event accordingly to a machine-adaptive process. The online logic 320 operates to seamlessly coordinate the event taking into account necessary constraints and behavioral inputs, in a data-driven approach.

FIG. 4 illustrates a further sequence diagram 400 of communications performed with event rescheduling using a machine learning model implementing online and offline logic, according to an example. As shown, the sequence diagram 400 includes features of the sequence diagram 300 described above for FIG. 3, including the users (302, 312), user devices (304, 314), and elements of the event scheduling services (320, 330, 340) and external data source 350.

In the example diagram 400 depicted in FIG. 4, User A 302 “requests” via the User A devices 304 (e.g., a mobile/wearable device of the user) to schedule an event 452 with User B 312. In response to the request 452, one of the User A devices 304 may transmit the request for the event 454 to the online logic 320. The request for the event 454 may be accompanied by the current state of User A 302, including any contextual information regarding the user's schedule, activity, or information from devices (e.g., sensor data).

In response to the request to schedule the event with User B 312, the online logic 320 gathers more information from User B 312. This information may be collected via a request 458 for a user state from one or more User B devices 314, and a response 462 that returns the current state data. Additionally, in response to the request to schedule the event with User B 312, the online logic 320 operates to request data 456 from one or more of the external data sources 350, such as weather, traffic, or event data types. The external data sources 350 return a data response 460 including current and future (e.g., projected) data for these data types.

The online logic 320 operates to provide a data model request 464 from a database 330 or other data store that hosts user-based machine learning models. Based on the characteristics of the users, the type of event, or state characteristics, the database 330 or data store returns a machine learning model and calculated data values 466 to consume the model. The online logic 320 then applies the calculated data, state data, and current and future data for the users and user activities into machine learning model, to determine schedule recommendations and predictions.

The schedule recommendations and predictions determined by the online logic 320 may be used to produce a plurality of ranked times for scheduling of an event, with such ranked times being communicated to the User B devices 314 with a communication 468 and output to the User B 312 with a data output 470. The plurality of ranked times for the scheduling of the event may be interacted with by the User B 312, to receive a selection of a time slot 472 with the User B devices 314.

In response to the selection of the time slot and other characteristics of the scheduled event, the User B devices 314 may communicate scheduled event details 474 for the upcoming event to User A devices 304, such as via electronic communication (including email, SMS, instant message, or like communication forms). In some examples, the scheduled event details 474 may be communicated in whole or in part to the User A devices 304 via the event scheduling service, an internet provider, or data service. Finally, based on the receipt of the schedule event details 474 at the User A devices 304 or the User B devices 314, a notification of the event may be output at the scheduled time. This may include a notification 476 at the scheduled time from the user B devices 314 to conduct the event with user A; and a notification 478 at the scheduled time from the user A devices 304 to conduct the event with user B.

FIG. 5 illustrates an example histogram 500 representing data used in machine learning model scheduling and rescheduling operations. For example, the histogram 500 depicts a modeling of the combined distribution of phone-calls that occur between two users, by hour of day. As shown, the two users tend to talk to each other between the working hours of 9 AM to 7 PM; with a majority of calls centered in mid-morning and late afternoons. This communication event activity between two users will be collected and analyzed as part of the offline data collection (e.g., depicted in FIG. 3), and integrated into a scheduling model of the user-based machine learning models.

FIG. 6 illustrates an example visualization 600 of a schedule implemented with model scheduling operations. This visualization corresponds a combined schedule of the users involved in the histogram 500 of FIG. 5. The visualization 600 of the schedule shows important meetings from 8 AM to 11 AM (indications 604, 606) and travel prior to these meetings (indications 602). As an assumption for this scenario, the users are unavailable or prefer to not to talk on the phone during a meeting.

In this scenario, the time slot 11:00-12:00 will be ranked high for a mutual phone call since the users tend to talk at this time and are available to talk. The 08:00-11:00 slot will be ranked low due to lack of availability in meetings, and 07:00-08:00 will be ranked low due to travel time and low incidence of calls between the users. Times between 12:00-15:00 will be ranked low since the users tend to talk less at these hours. As result, a proposed call may be automatically scheduled at 11:15 (indication 608), to allow conclusion of the prior meeting, and a schedule opening for the user during a lunch hour (indication 610).

Based on this automatic ranking and scheduling, a smart events timeline may be constructed and output to the user. A user may perform interaction functions such as adding reminders, updating events, and adjusting and recalculating a timeline, using time-based and activity-based semantic recommendations.

FIG. 7 illustrates an example chart representing data used in machine learning model scheduling operations. The chart specifically shows a user's distribution of phone calls by Activity/Means-of-Transport: 80% of the phone calls are performed while the user is In-Vehicle (indication 710), whereas 20% are performed while the user is Stationary (indication 720). In the scenario visualized by the chart, a semantic concept associated with the identified activity, such as “Next Drive”, will be ranked high for a phone call. In a further example, an unsuccessful caller may be notified that the call will be scheduled to the next drive (without a specific hour). The caller will be reminded to call once beginning the activity.

FIG. 8 illustrates a flowchart 800 of a method performed by an event scheduling service for performing contextual event scheduling using a machine learning model. In an example, the method of flowchart 800 is executed by a system including a remote computing device (e.g., server computing device), which comprises processing circuitry to perform the respective operations. However, it will be understood that the following techniques may be modified for additional or substitute processing actions at another data processing system or service, or a client user-operated device (e.g., smartphone or wearable device).

As shown, the flowchart 800 includes operations for programming offline logic used in a data model. These may include operations that collect data from external state sources (operation 810) and collect data from one or more user devices (operation 820), used as training data. Based on the training data, the machine learning model may be modified based on user and event availability, and the modifications to this machine learning model may be stored accordingly (operation 830). These operations for training may occur prior to a request for scheduling or rescheduling of a particular communication event (or, after the performance of a particular communication event, to provide updated training data for use in processing future requests).

The flowchart 800 further includes the depiction of operations at the event scheduling service (operations 840-890) for processing of an event scheduling request. The processing of the event rescheduling request may be initiated with the receipt of an indication of an event scheduling for a particular user communication event (operation 840), such as with a meeting request, phone call request, or like indication for an electronic communication event (e.g., in a communication or messaging software program). In response to the indication of the event rescheduling, the event scheduling service operates to retrieve or determine constraints of the scheduling (e.g., initiating) user, the other user, and other users involved in the prospective electronic communication event (operation 850). Additionally, the event scheduling service operates to retrieve or determine various activity and behavioral inputs of the users involved in the prospective electronic communication event (operation 860).

The constraints and behavior inputs that are determined for the users are used to determine a proposed event scheduling time and parameters (operation 870). These characteristics of the proposed event may also correspond to action options that are displayed and output as a contextual or semantic option (such as “conduct phone call after arriving at office”). The characteristics for the event scheduling time and parameters for the proposed event are then communicated to respective users (operation 880). In further examples, the time and scheduling parameters for a proposed event is provided as one of a plurality of ranked options, which may be selected or interacted with. Finally, in some examples, the scheduling service may facilitate the electronic communication event between the users via one or more electronic communication mediums (operation 890).

FIG. 9 illustrates a flowchart 900 of an example method performed by a user device for contextual event scheduling with an event scheduling service. In an example, the method of flowchart 900 is executed by a system including a user-operated device (e.g., mobile computing device), which comprises processing circuitry to perform the respective operations. However, it will be understood that the following techniques may be modified for additional or substitute processing actions at the user-operated device, another user-operated device (e.g., wearable device), or a remote computing device (e.g., an event scheduling service or server).

As shown, the flowchart 900 begins with the receipt, at a user device, of an indication of a request for scheduling a communication event with another user (operation 910). This indication may be provided in a call or meeting request, a notification from a communication agent, or the like. In response to this indication, the user device requests an event scheduling time from a scheduling service (operation 920). The request for the event scheduling time to the scheduling service may be accompanied by the transmission of user contextual information such as activity data (operation 930).

In response to the request, the user device receives an event scheduling time and event scheduling parameters from the scheduling service (operation 940). This may correspond to the scheduling service communication (operation 880) discussed in FIG. 8. Based on the received event scheduling time and event scheduling parameters, at least one of event selection options are output to the user via the user device (operation 950). The user device then may receive a selection of the top ranked event action option (e.g., “Call after Meeting”, if it is determined that the user is in a meeting), or the selection of an alternate event action option (e.g., “Call in Evening”) (operation 960). The communication event may then be performed at the scheduled time, based on the conditions and characteristics of the selected event action option (operation 970).

FIG. 10 is a block diagram illustrating an example system 1000 including a user computing device 1010, a wearable device 1030, and a server 1040, implementing circuitry and structural electronic components that may be configured for implementation of the techniques described herein. In accordance with the previous described configurations, the system 1000 may have these devices operably coupled (e.g., communicatively coupled) with one another, but it will be understood that additional components (other wearable devices, sensors, databases, and processing components) may be integrated at a variety of locations in the system. Further, the capabilities of the user computing device 1010 and the wearable device 1030 may be integrated in some examples into a single apparatus (e.g., a smartphone with built-in sensors).
